ELECTRICAL SYSTEM or DISTRIBUTION.

Specification of Letters Patent.

Patented Feb. 3, 1914.

To all whom it may concern:

Be it known that I, HUGH HAznL'ron, a citizen of the United States, anda resident of Englewood, county of Bergen, and State of New Jersey, have invented certain new and useful Improvements in Electrical Systems of Distribution, of which the following is a specification.

My invention relates to electrical systems of distribution and more especially to lighting systems for passenger or other coaches for railroads which use electrical apparatus as a source of motive power. In such systems the various lamps or translating means may be supplied from the same source of power which supplies the propelling means for the coaches or train. It will be apparent, however, that upon failure of the main source of power the translating devices will not be fed and the coaches will be left in darkness.

One object of my invention is to provide economical and efiicient means whereby upon failure of the main source of power in such systems a certain number of lamps or translating means will still be sup lied so that the coaches will be lighted su ciently.

Further objects, features and advantages will more clearly appear from the detail description given below taken in connection with the accompanying drawing which shows one form of my invention.

.Referring to the drawing, 1 represents a main generator having one terminal connected to the ground at 2 and having its other terminal connected to a suitable trolley or third rail 3. From the conductor 3 power is taken by means of a conductor 4 to-the coach or train to sup 1y power for '1 the propelling means thereo and also to supply light therefor.

5 represents a double pole switch, one pole of which connects the set of lamps 6 to the conductor 4. The lamps are arranged in multiple series there being six parallel circuits of five lamps each. The other terminal of the lamps is connected by a conductor 7 to one terminal 8 of a snap switch 9. When the switch 9 is thrown in connection with the terminal 8 the conductor 7 is placed in electrical connection with the terminal 10 and conductor 11. The completion of the circuitis made through conductors 12 and 13 to the ground 14 by any suitable means, such as the wheels of the coaches. In series between the conductors 12 and 13 is placed a storage battery 15 and in series with the conductor 12 is a fuse 16.

17 represents an auxiliary set of lamps or translating means, there being four lamps in parallel with each other, one terminal of these lamps is connected to the battery 15 by conductor 18. The other terminal of the lamps 17 is connected to the other pole of the double pole switch 5 by a conductor 19. From'the double pole switch 5 the circuit leads to the conductor 11 by means of a con ductor 20,-a fuse 21 being included in scries in the conductor 20.

The third terminal 22 of the snap switch 9 is connected to terminal 8 by conductor 23 and the fourth terminal thereof, 24:, is connected to the conductor 13 and the ground by means of conductor 25. From the conductor 11 leads a conductor 26 which supplies a circuit 27 which may be used in operating door signals of-the coaches, and a circuit 28 which may be used to operate the engineers valve and electric trip. Fuses 29 may be included in each of the circuits of the lamps 6.

The set of lamps 6 may consist of 30 10 candle power, 107 volt lamps,'while the set of lamps 17 may consist *of 1 70 volt lamps. The battery 15 may be arranged with 30 cells to have a voltage of 65 volts, and under these conditions the source of power should furnish a voltage of approximately 600 volts.

The operation of the system is as follows: Under normal conditions the set of lamps 6 is supplied with current from the source of power 1 through theconductors 3, 4, 7, switch 9, conductors 11, 12, 13 and 14, the battery 15 beingincluded in series in this circuit and therefore arranged to be charged by the source of power 1. The auxiliary lamps 17 will also be supplied with current from the source of power 1, since they are connected in shunt 111 a parallel circuit to the battery 15. If, however, the source of power 1 should fail then the set of lamps 6' would no longer operate and the battery 15 would no longer charge, but the battery 15 will then furnish current to the lamps 17 through the conductors 12, 20, 19 and 18, so that the coach or coaches will not be left in darkness and suflicient light will be had. If it is desired for any reason to disconnect the battery to replace the same or for any other purpose the snap switch 9 may be operated to disconnect the terminals 8 and 10 and to connect the terminals 22 and 24-,

In this-manner the set of lamps 6 connected directly to the groundlt by a conductor 25 and the circuit from the source 1 through the battery 15 and lamps 17 is open, so that the generator 1 will no longer supply current to these. v

Various fuses 16 21 and 29 ,are included for purposes well known in the art. The auxiliary circuits 27 and 28 are connected across the battery l5,sotl1at case of failure of the main source 1 these circuits may still be energized.

from the above it will be clear that I have provided .a simple, economical and efficient .arrzmgement for the lighting of coaches, especially those in which electric vmotive power is used and the source which i supplies the motive power is also used as a source for su plying the lighting devices.

Although l ha-ve described my improvements in great detail, nevertheless it do not desire to be limited to such details, except as specified in the claim, but

Having thus fully clearly described l sameness my invention, What I claim as new and desi're to secure by Letters Patent, is:

in an electrical system of distribution, a source of -poWer,- translating devices supplied thereby, a storage apparatus arranged to be charged in series With said translating devices, other translating devices connected across the storage apparatus whereby upon failure of the soua'ce they Will be supplied by the storage apparatus, a switch arranged to disconnect the storage apparatus but still maintain a the first mentioned translating means in circuit with the source, and a double pole switch having one Ipole in series with the first mentioned trans ating means,

and the other pole in series with the second mentioned translating means between said second mentioned translating means and the storage apparatus.

in testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
